Abstract

PURPOSE: To raise the efficiency of lining as well as shorten the curing period for cement mortar by the procedure in which an indeterminate refractory is supplied in the dry state to a watering portion near the end of an air flow pipe and then water and a setting accelerator are added to the refractory.
CONSTITUTION: A mixture of cement and sand or its similar undeterminate refractory is quantitatively supplied to the inlet side of the air flow pipe 1 by a quantitative feeder, preferably by the continuous quantitatively supplying feeder F and then fed pneumatically in the dry state to a position near the watering portion 2, located near the end of the pipe 1, through the pipe 1. On the other hand, water is supplied from the watering jacket 2a to the watering portion 2, during which period a setting accelerator is added to the undeterminate refractory inside the air flow pipe 1. Afterwards, the refractory is sprayed onto the inside surface of the pipe P (e.g., hot air duct) to be lined by a sprayer at the end of the air flow pipe 1.
